“In hilchos tzadaka it states that if you give tzadaka unwillingly, you lose all your reward.”
Supporting able-bodied people who choose to learn instead of work does not qualify as tzedaka, which one is obligated to give. It’s considered instead “hachzokas haTorah”, which is not mandatory.
It’s a very sad situation when Jews can accept support from other Jews and not even have the slightest feeling of gratitude. It raises serious questions about their supposed learning.
